= Resource considerations
|
||
|
||
[role="_abstract"]
|
||
Review the resource considerations table, which provides baseline examples for configuration settings, such as eBPF memory limits and LokiStack size, tailored to various cluster workload sizes.
|
||
|
||
The following table outlines examples of resource considerations for clusters with certain workload sizes.
|
||
|
||
[IMPORTANT]
|
||
====
|
||
The examples outlined in the table demonstrate scenarios that are tailored to specific workloads. Consider each example only as a baseline from which adjustments can be made to accommodate your workload needs.

1. Tested with AWS M6i instances.
|
||
2. In addition to this worker and its controller, 3 infra nodes (size `M6i.12xlarge`) and 1 workload node (size `M6i.8xlarge`) were tested.
